RADIATOR.

SPECIFICATION forming part of Letters Patent No. 716,906, dated December'30, 190 2% hpplication filed March 24, 1902. Serial No. 99,568. (Nomodel.)

To aZZ whom it may concern:

Be it known that I, ALFRED EDWARD LAY- COCK, a subject of the King ofGreat Britain,

residing at Moosoniin, county of Assiniboia, North-West'lerri-tories,Oanada,haveinvented certain new and useful Improvements in Radiators;and I do hereby declare that the following is afull, clear, and exactdescription livering it in the form of hot air into an apart mentor roomand likewise to radiate the heat therefrom, so as to assist in heatingsaid room.

My improved radiator is adapted either to be used in addition to thestove in the same apartment therewith and immediately thereover, wherebyto increase the capacity of the stove for heating the apartment, or itmay be placed inan upper apartment through which the flue pipe of thestove is carried and whereby the stove is enabled to heat simultaneouslytwo apartments without any additional appliances, such as hot-air andcoldair boxes, registers, steam-circulating means and the like, whichgreatly add to the expense of heating a house.

Myinvention consists, essentially, inan enlargement of the Stovepipecomprising a pcculiar arrangement of concentric cylindical or annularchambers, which are adapted alternately to contain the smoke or fluegases and to form circulating passage-ways through which the air of theroom is adapted to pass.

My invention :further consists in the peculiar combination andconstruction of parts hereinafter more specifially set forth, and whichwill be particularly pointed out in the claims.

In the drawings formingapartof this specification, Figure 1 represents avertical crosssection through a house, showing a stove with my improvedradiator in the flue-pipe thereof in elevation. Fig. 2 is a centrallongitudinal sectional elevation of my improved radiator as usuallymounted, and Fig. 3 .is a similar view showing my improved radiator asreversely mounted and provided with an attachment particularly fit-tingit for use with hard-coal fuel.

ported upon a foundation 8. The stove adapted to heat the lowerapartment is indicated I j at 9, and it has a vertical flue-pipe 10,extending upwardly through the floor-.6 and into the upper apartment 5,and in that part which extends through the apartment 5 is provided myimproved radiator, (designated by the numeral 11.) As herein shown, thisradiator comprises a cylinder of sheet-iron 12, considerably exceedingthe diameter of the stovepipe' and connected. therewith by reducedconical ends 13, having parallel flanges 14:, into which the ends of theStovepipe 10 telescope. In the interior of this sheet-iron cylinder islocated a similar but smaller concentric cylinder 15, which is solidlyconnected to the outer. cylinder by a pair of short cylindrical openings16 at opposite extremities of a diameter located at the upper end, and

a similar pair 17, located at the lower end thereof, thus connectinginteriorly the cylinder l5 witlrthe exterior of the radiator, whileseparating both from theintermediate annular space 18. Within thecylinder 15 there is another concentric piece 19, herein shown assomewhat conical in form, and tapering smaller toward the top, as I havefound this form gives improved results in a manner which will be statedpresently. This cone 19 is of slightly less length than the cylinder 15and is connected therewithat top and bottom by dished annular plates 2021, respectively, thus forming an annular closed chamber 22 between thecylinder 15 and cone 19 of roughly quadrangular section, which chamberis connected with the outside air of the apartment by the apertures 16and 17, as above mentioned. The inner conical space 23, formed withinthe cone 19, is subjected to the action of the fluegases which passtherethrough, and its upper end is suitably closed by a damper in theform of a butterfly-valve 24:, having a shaft 25, which is pivoted at 26in the walls of the cone,19 and extends upwardly through one of theapertures 16 and is provided with a cross-bar 27 to form a handle forturning the valve.

The flue-gases in passing up through the flue-pipe 1O impinge upon thedished plate 21 and are separated into two portions, one passing aroundthrough the annular chamber 18 and the other passing up through theconical chamber 23, and in both cases they part with a portion of theirheat to the outside air of the apartment and to that which circulates inthe air-chamber 22. These two portions of the fine-gases again join oneanother in the upper cone 13 of the radiator and pass out through thecontinuation of the flue-pipe 10, as indicated by the arrows. Theairinlets 17, being separated by a quarter-circle from the air-inlets16, cause more thorough circulation of the air through the inner chamber22 than if they were located one above the other.

In Fig. 3 I have shown precisely the same device as in Fig. 2, and it isaccordingly indicated by the same reference-numerals; but I have alsoshown in addition a funnel-shaped member 28, which is inserted throughthe upper end of the radiator within the flue-pipe,

as I have found this arrangement specially advantageous when hard coalis burned in the stove, because it causes a longer period of radiationand more thorough circulation of the flue-gases around the air-chamber22 than where the upper end of the chamber 23 is simply open. Thistherefore illustrates the fact that myimproved radiator is reversible,and its two opposite positions are suitable for different conditions, aswill be found by experience.

The object in having the plates 20 21 dished or concave is that itgreatly strengthens the air-box in the flue and prevents warping ordistortion of the metal in great heat.

While I have shown in the accompanying drawings the preferred form of myinvention, it will be understood that I do not limit myself to theprecise form shown, for many of the details may be changed in form orposition without affecting the operativeness or utility of my invention,and I therefore reserve the right to make such modifications as areincluded in the scope of the following claims.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A flue-radiator comprising a cylindrical casing having conical endsadapted to telescope into the flue, an air box or chamber supportedtherein having a concentric cylindrical outer wall, a concentric conicalinner wall and dished annular end plates, a pair of passages formingsupporting means for the air-chamber at opposite extremities of adiameter connecting the interior of the air-chamber with the outside airand at one end thereof, another pair of passages connecting the interiorof the air-chamber with the outside air at the other end thereof, thelast-named pair of passages being at an angular distance of ninetydegrees from the first-named pair, and a damper operated by a handleextending through one of said passages, said damper closing the interiorpassage for the flue-gases.

2. A flue-radiator comprising a sheet-metal cylinder having conicalreduced ends, an annular cylindrical air-box supported concentrically insaid cylinder whereby to divide the flue-gases into two portions, adamper closing the inner passage-way for the fluegases,circulating-apertures connecting the interior of the air-box with theoutside air, and a funnel-shaped pipe depending from the upper end ofsaid radiator.

3. A flue-radiator com prising a cylindrical casing adapted to form aportion of a flue, an air box or chamber supported therein having aconcentric cylindrical outer wall, a concentric conical inner walltapered from top to bottom and dished or concaved annular end platesconnecting said walls, in combination with a conical baffietubesuspended from the upper end of the casing and depending within saidinner conical wall and having its sides approximately parallel thereto,substantially as described.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
